CHECK-ROWER ATTACHMVENT FOR CORNiPLANTERS.

SELCIFICATION forming part of Letters Patent No. 281,469, dated July 17, 1888.

Application filed May 7, 1881. (Model.)

.To aZZ whom it may concern:

Be it known that L'ANDREW F. DICE, of Joliet, in the county of Will and State of Illinois, have made a new and useful Improvement in Check-Bower Attachments for Gorn- Planters, of which the following is a specication.

My invention relates to the construction and arrangement of a device in check-row attachments by means of which the corn may be dropped in checks or rows at regular intervals by means of the knotted cord or wire.

In the accompanying drawings, which form a part of this specification, Figure l is a plan view. Fig. 2 is an .end view of the cross-head bar. Fig. 3 is an end view; Fig. 4, an end View of the seed-bar connections. Fig. 5 is a side elevation of the slotted oscillating plate, and Fig. 6 is a top view of the indentated plate upon which the slotted oscillated plate oscillates.

Like letters of reference made use of in the several figures indicate like parts wherever used.

Referring particularly to the drawings, A-

passes, which wire is Vheld in place by means.

of the finger j and the friction-roller a3. As the knotted cord or wire passes over the grooved guide-wheels c and a', the said knots become engagedwith the forked lever c', causing said lever to be carried backward with said knot until it reaches the stop L on the circular travel-bed c. When said knot passes through the flared portion of the forked lever c', as shown by the dotted lines in Fig..l, it becomes disengaged from the forked lever c', allowing said lever to be drawn back to its former .position by the spring s. As the lever c is carried backward by means of said knotted cord or wire, it presses against the flange of Athe angular lever c2, causing said lever to operate.

R represents the connecting-rods, attached at one end to the angular lever c2, and terminating at their other extremities in the slots F of the slotted oscillating plate H. As the said lever c2 is operated, it causes the connectingrod R to be moved outward, which movement also causes said oscillating plate to be oscillated. In this connection it may be noted that either end of this device and the movement of the connecting-rods R, as shown in Fig. 1,are identical. When the connecting-rod Ris caused to move outward by means of the forked lever c', said movement also causes said oscillating plate H to assume a position opposite to that which is represented in Fig. l. The inner movement of said connecting-rod R is produced by the contraction of the spring S.

When the rod R is forced back or in by the contraction of the spring S, it assumes a position in the slot F opposite to its former position, and in the opposite end of the slot F. This position is caused by the slot F assuming a'n opposite position from the one formerly occupied, and the pressure of the rod R against the inclined surface of the slot F by means of the contraction of the spring S caused by said slot F being reversed in an opposite position from the one it formerly occupied. When one end of this device is in active operation, the opposite end, with the exception of the lever c', is forced to operate by means of the rod R being connected to the oscillating plate H in the slot F. When said oscillating plate H operates, it causes the arm Kl to operate, which armK is connected with the oscillating plate H by means of vthe post or standard K, as shown in Figs. l, 3, and 5. The said arm K is provided with a slotted plate, K2, which plate is connected at its slot with the primary rod n of the seed -barconnecting rods, as shown in Fig. 1. The said rod n, being connected in the slot of the plate K2, is allowed to remain stationary until the opposite end of the slot is brought to bear against said rod n, causing it to receive a sudden movement, operating the seed-bar in the same manner as if operated by hand. The said seed-barconnecting rods, as represented in Figs. 1 and 4, are constructed of a primary and a secondary rod, held firmly in position by means of the clamp-block m and the flat metal bar a2, attached to the lower portion of the clamp-block m, for the purpose of holding the lug of the secondary rod a in the receptacle of the seedbar, said clamp being so constructed that the rods may be lengthened or shortened at pleas- IOO ICL

ure, and the lugs on said bars being of different sizes to be received by different receptacles.

The grooved guide-wheel a is so constructed that it may be overturned by means of the hinge N in its standard c, so as to dump the knotted cord or wire from the forked lever c and itself. The grooved guide-wheel a still retains the knotted cord or wire, as shown in Fig. 3, until said cord or wire may become disengaged from said wheel aby means of drawing said knotted cord or wire at an angle, caused by turning` of this device. Said grooved guide-wheel a is held in position and kept from being overturned by means of the clamp a2, hinged to the cross-head bar, as shown in Figs. l, 2, and 3. \Vhen it is desired at the end of the route to have the knotted wire become disengaged or dumped from the device, the operator may press or pull down on the cord I), which cord passes through the eye e, which eye is attached to the stop-block J, and also passes downward and connects with the clamp a2, said pressure ofthe operator causing the clamp a* to be raised away from the standard portion of the grooved guide-wheel af', allowing said wheel to be thrown over by the pressure of said knotted cord o1' wire, as shown in Figs. 2 and 3. This cord may be attached to any desired portion of the planter to which this attachment may be connected. The stop-block J, which is attaehed to one end of the circular travel-bed c, is preferably constructed of wood, so that the eye c may be easily attached, and it resists considerable of the `jar of the forked lever c.

In Fig. 5 the indentations B of the plate I are illustrated, so as to represent the position of the rods R, which project in vand through the slots F of the oscillating plate H and the indentations in the plate I). Said indentations B of the plate I) are for the purpose of receiving and retaining that portion of the rods R which terminates inthe slots F and in said indentations after said rods R have been forced back to their positions by the contraction of the spring S, and also to hold the said rods R in their proper positions while they are being operated by means of the forked lever c, and as the rod R is carried out it becomes disengaged from the indentation B by passing up over its inclined surface.

The standard or post K is so arranged that it may be reversed from the under portion of the device to the upper portion, where it may be necessary in making connections with different seed'droppers, as shown by the dotted .lines in Fig. 3. The clip x, as represented in Fig. l, is so arranged that it bears against the connectingrod R, thus holding it in its proper position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a check-row attachment, the combination, with the frame and the connecting-rods, of au oscillating plate, H, provided with slots to receive the connecting-rods, substantially as set forth.

2. In a check-row attachment, the combination, with the frame and connecting-rods, of the bell-crank lever c?, the spring S, and the lever c', substantially as set forth.

3. In a check-row attachment, the combination of the levers c and c2, spring S, the connecting-rods R, and oscillating plate H, substantially as set forth.

4. In a check-row attachment, the combination of the levers c and c2, the hinged standard c, and the lever a2, substantially as set forth.

5. The combination, with the bell-crank lever c2, lever c, and the connecting-rods, ofthe grooved wheels a and a', arranged at right angles to each other, as set forth.

6. The combination, with the slotted oscillating plate H, having the standard K, ofthe arm K and slotted plate K2,'substantially as set forth.

7. rIhe combination, with the oscillating plate H, and the slotted arm K, and plate K2, of the rods n and n', the fiat bar n2, and the 'clamp in., substantially as set forth.

8. The combination, with the rods R and the oscillating plate, of theplate I?, having the indentati ons or cut-away portions B, as and for the purpose set forth.
